Support for eXFlash: 1.8" solid state drives
In addition, the x240 supports eXFlash with up to eight 1.8-inch solid-state drives combined with a
ServeRAID M5115 SAS/SATA controller (90Y4390). The M5115 attaches to the I/O adapter 1 connector
and can be attached even if the Compute Node Fabric Connector is installed (used to route the Embedded
10Gb Virtual Fabric Adapter to bays 1 and 2, as discussed in "I/O expansion options"). The ServeRAID
M5115 cannot be installed if an adapter is installed in I/O adapter slot 1.
The ServeRAID M5115 supports combinations of 2.5-inch drives and 1.8-inch solid state drives:
Up to two 2.5-inch drives only
Up to four 1.8-inch drives only
Up to two 2.5-inch drives, plus up to four 1.8-inch solid state drives
Up to eight 1.8-inch solid state drives
The ServeRAID M5115 SAS/SATA Controller (90Y4390) provides an advanced RAID controller
supporting RAID 0, 1, 10, 5, 50, and optional 6 and 60. It includes 1 GB of cache, which can be backed up
to Flash when attached to the supercapacitor included with the optional ServeRAID M5100 Series
Enablement Kit (90Y4342).
